@HexHammer,
NAACP may have some kind of point, maybe- If all we humans ever know if life, then in some sense life can be said to be "infinite". the only experience we ever have is of life itself, we have no other experience, only experience within life, and so life can be said to be "infinite" in a subjective sense, although this does sound slightly odd.
whether we can be said to be the being from birth to death is contentious though; what constitutes being the same being throughout our lives? psychologically we are quite changeable, and even biologically we change over time, we digest food, of which part of that "becomes a part of us" is a sense, and so our being isn't fixed, neither psychologcially or biologically.
